Non-productive time down, productivity up
In aluminum machining processes, non-productive times are often longer than the pure machining or main times. The larger the workpieces are, the longer the distances the feed axes have to cover, for example during a tool change. The rule of thumb is: the more complex the machining and the larger the workpieces, the greater the proportion of non-productive time. A linear motor as a drive achieves a higher speed than a motor with rotor and stator, whose rotary motion must be mechanically converted linearly. Furthermore, due to its operating principle, a linear motor works wear-free in every application.
We know these relationships and have been relying on the use of the linear motor for many years. With the help of the higher dynamics and speed of linear motors for straight-line movements in combination with the weight-optimized design, we minimize these non-productive times in our CNC machining centers compared to axes with servo motors. Simply put, SW’s CNC machining centers with linear motors are the fastest in the world.
